Application filed June 2, 1925, Serial No. 34,422. Renewed December 19,1927.

This invention relates to side frames for railway car trucks and moreparticularly to the reinforcement of the ends of cast side frames.

The principal object of my invention, generally considered, is'thereinforcement of the union between compression and tension members atthe ends of cast side frames for railway car trucks. An object of myinvention is the strengthening of the junction between the compressionand tension members at the ends of side frames for railway car trucks,which side frames may be provided with integral journa1 boxes by carryinflangesfrom the tension member beyon the junction of the compression andtension members, said flanges being preferably formed in line with thegeneral direction of the tension member.

Another object of my invention is the strengthening of the connection orjunction at the ends of side frames for railway car trucks adjacent theunion with integral journal boxes, and particularly in connection withcast frames in which the compression and tension members are formedgenerally U-shape in cross-section and in which each member comprises aweb and flanges at opposite sides of said web, ribs being provided inline with the upper edges of the flanges on the tension member andextending from below the intersection of the compression membertherewith to above said intersection and extending for a'materialdistance along the outer ends of the compression member.

Another object of my invention is the provision of reinforcing ribs onthe outer faces of side frames for railway car trucks, said ribs beinglocated adjacent the junction between compression and tension membersand extending preferably in line with the upper edges of the tensionmember from below to above the junction of the compression membertherewith and preferably being swelled or increased in strength atapproximately said junction and decreased 'in both directions therefrom.

Other objects and advantages of the invention will become apparent asthe description proceeds.

Referring to the drawings illustrating my invention, the scope whereofisdefined by the claims:

Figure 1 is a fragmentary side elevation of one end of a side frame forrailway car trucks embodying my invention; and

Figure 2 is a fragmentary plan view of the side frame as illustrated inFigure 1.

Referring to the drawings in detail, like parts being designated by likereference characters, I have shown one end of a side frame 1 for railwaycar trucks, the remainder of said frame not involving features of mypresent invention not being illustrated.

In the embodiment shown the frame comprises a compression member 2 andtension member 3, the ends of said com ression and tension members beingintegral y united at 4, as is usual in cast side frames, and preferablyformed with a journal box 5 adjacent the point of union betweencompression and tension members at the ends of the frame.

The frame 1, as will be understood, is symmetrical on either side andmay be formed, as is usual, with bolster column or strut portionsspacing intermediate portions of the compression and tension members.Such features, however, not being part of my invention and well known tothose skilled in the art, are not illustrated.

The compression member 2 and tension member 3 extends substantially thefull length of the side frame, as will be understood, and at each end ofsaid side'frame there is provided a journal box 5 preferably integraltherewith. Said compression and tension members in the presentembodiment are each formed generally U-shape in crosssection with a mainweb portion 6 and flange portions 7 on opposite sides of the webportion, said flange portions, in the embodiment shown, extendinginwardly or toward each other. The free edges of the flange portions 7may be thickened or provided with rib or bead portions 8 extendingtherealong.

From a consideration of the drawing, it will be apparent that in thepresent embodiment the tension member is formed with a bottom web andupstanding flanges at opposite sides of said web, whereas thecompression member comprises an upper or top web with depending flangeson opposite sides I thereof. The outer portions of the web 6 of thecompression member 2 are preferrably sloped downwardly and outwardly andcurved to connect with the outer wall of ill . if desired, .asillustrated, by cutting away a portion of the web 6 of the compressionmember adjacent the connection with the journal box. The correspondingflange portions 7 of the compression and tension members 2 and 3 mergeinto each other, at 10, to form a box-like portion over each journalbox.

The union between the web 6 of the tension member 3 and the journal boxis preferably made by curving said web slightly at 11 to anapproximately horizontal position and joining it with the roof or upperwall 12 of the journal box. The central portion of the web at this pointmay be cut away at 13, if desired, to lighten the construction.

Approximately triangular reinforcing webs 14 may be provided between theouter portion of the web 6 of the tension member and the inner wall 15of each journal box. The junction between the compression and tensionmembers is reinforced by flanges or rib portions 16 in line with theupper edge of the flange portions 7 of the tension memher 3 andextending from below the junction 4 between the compression and tensionmembers to above said junction, as illustrated. These flanges or ribs 16preferably increase in depth, width or strength from the ends thereof toa maximum ad acent the junction 4 between compression and tensionmembers.

Although the flanges or ribs 16 are shown on the outside faces of theside frame, they may be formed on the inside faces thereof instead of,or in addition to, being formed onthe outside faces thereof.

From a consideration of the drawings it will be apparent that theseflanges or ribs are referably formed as enlargements and contlnuationsof the thickened or beaded portions 8 forming the upper edges of theflanges on the tension member 3. The ribs or beading 8 on the loweredges of the compression member preferably curve around the junctionswith the tension member as indicated at 4, and merge with the ribs 16.Although the reinforcement flanges are shown as extending nearlyentirely across the outer ends of the compression member 2, I do notwish to be restricted to the exact length of said flanges as saidlength, as well as the depth, width or strength thereof, may beincreased or decreased according to circumstances. Such a reinforcement,however, as

illustrated, which merely adds a slight proportion of material to theframe, will greatly increase the strength thereof because saidreinforcing flanges or ribs are positioned at critical portions of theframe.
